2 Nursig staff i the iteral medicie ad surgical uits of teachig hospitals: compositio ad cost INTRODUCTION I recet decades, the social, political ad ecoomic ladscape has prompted the pursuit of maagemet strategies capable of recocilig budget costraits with improvemet of products ad services offered to populatios. Health istitutios also face the challege of efficiet use of resources while also improvig the service provided to their users. I Brazil, these istitutios are experiecig major hardships due to lack of ivestmet i ifrastructure ad the workforce, combied with the icreasig health eeds of the populatio. Problems related to maagemet ad traiig of huma resources are cosidered oe of the mai factors i deterioratio of health care services (1). The primary measures adopted by maagers i this sector i their efforts to tackle risig costs ofte result i quatitative ad qualitative limitatios i ursig staff, creatig work overloads that hider the orgaizatio ad executio of care processes ad stad i the way of promotig measures to ehace quality of care ad the safety of users ad care providers (2). The istitutios ofte fail to meet the miimum ursig staff parameters recommeded i Resolutio No. 293/04 of the Federal Coucil of Nursig (COFEN) (3). Kowledge eeds to be geerated to assist i the decisio-makig process ivolvig ursig staff adjustmets ad the costs they would etail, thereby helpig to guide huma resources policies ad trasform maagemet processes i health istitutios. From this perspective, this study sought to evaluate the mea quatitative ad qualitative ursig staff workig i the iteral medicie ad surgical uits of three public geeral teachig hospitals i the city of São Paulo, compared to the projected mea staff parameters recommeded i COFEN Resolutio No. 293/04, as well as measure the average cost of the ursig staff, both curret ad projected, as per this Resolutio. METHOD A quatitative, descriptive, exploratory study, utilizig prospective data collectio, coducted i the iteral medicie ad surgical uits of three public geeral teachig hospitals, referred to as Hospital A, Hospital B ad Hospital C, i the city of São Paulo. This study was approved by the Research Ethics Committees of the School of Nursig of Uiversity of São Paulo (Process No. 1110/2011). Two uits were aalyzed i Hospital A, three i Hospital B ad five i Hospital C. Data were collected betwee August 2012 ad July The study populatio cosisted of ursig professioals (urses ad ursig techicias/aides) ad patiets hospitalized i the selected iteral medicie ad surgical uits. Calculatio of the quatitative ad qualitative daily meas for professioals i the uits The daily mea of urses ad ursig techicias ad aides workig i the uits durig each moth of the period from August 2012 to July 2013 was calculated through the followig equatio: Q k = Q d=1 k(d) d Q k = daily mea umber of professioals from category k workig i the uit; d Q k(d) = sum of the daily umber of professioals from category k workig i the uits o d = 1, 2, 3... days of the sample, obtaied through the mothly work shift records; k = professioal category beig aalyzed (urse, ursig techicia or aide). Projectio of the quatitative ad qualitative daily mea of professioals eeded for the uits The followig calculatios were employed: Idetificatio of the daily mea umber of patiets accordig to the degree of ursig depedecy: The researchers, i partership with the ursig team providig the care, classified the patiets accordig to the degree of ursig depedecy, usig the patiet classificatio system (PCS) desiged by Fuguli (4). The mea umber of patiets accordig to type of care was calculated usig the equatio: j = TO L j 100 j = daily mea umber of patiets accordig to type of care j (miimum, itermediate, high depedecy, semi-itesive ad itesive); TO = mea mothly occupacy rate i the uits, from August 2012 to May 2013; L j = umber of beds, accordig to type of care j (miimum, itermediate, high depedecy, semi-itesive ad itesive). The calculatio of the mea recommeded daily workload of ursig professioals, accordig to COFEN Resolutio No. 293/04 11, was obtaied through the equatio: C j = j h j C j = mea daily workload accordig to type of care j (miimum, itermediate, high depedecy, semi-itesive ad itesive); = mea daily umber of patiets accordig to type of care j (miimum, itermediate, high depedecy, semi-itesive ad itesive); h j = mea recommeded daily hours of care accordig to COFEN Resolutio No. 293/04 (3) (miimum, 3.8 hours; itermediate, 5.6 hours; high depedecy ad semi-itesive, 9.4 hours; itesive, 17.9 hours). The calculatio of the mea umber of professioals accordig to category was obtaied by applyig the followig equatios: Q= j=1 C j t 48 Rev Esc Eferm USP 2015; 49(Esp2):47-53

3 Q = mea daily umber of ursig professioals required; j=1 C j = sum of the daily mea workloads accordig to types of care (miimum, itermediate, high-depedecy, semi-itesive ad itesive); t = daily workig hours. The umber of urses was calculated usig the proportio recommeded i COFEN Resolutio No. 293/04 (3) for this professioal category. Q ef =Q P ef Q téc/aux =Q (1-P ef ) Q ef = mea daily umber of urses; Q = mea daily umber of ursig techicias/aides; P ef = mea proportio of urses (miimum ad itermediate care, 33%, high-depedecy ad semi-itesive care, 42%, ad itesive care 52%); Q téc/aux = mea proportio of ursig techicias ad aides (miimum ad itermediate care, 66%, high-depedecy ad semi-itesive care, 58%, ad itesive care 48%). These calculatios eabled compariso of mea umber of curret urses ad ursig techicias/ aides with the projected umber for the iteral medicie ad surgical uits accordig to official parameters. Data o ursig staff costs came from the persoel departmets of the hospitals, which set spreadsheets with the mea payroll costs for urses ad ursig techicias/aides durig the study period. The spreadsheets cotaied records o the umber of professioals, base wages, social security paymets, bouses ad beefits, by fuctioal category. Aual wages were calculated by totalig wages, charges, beefits ad bouses; that was total was divided by the umber of professioals, by category, to obtai mothly wages. To determie the mothly mea hourly costs per category, the mothly mea wage was divided by the umber of hours worked, accordig to the cotracts for each hospital. The variace i the umber of projected professioals (NPP), accordig to the categories, i relatio to the umber of curret professioals (NCP), as well as the variace i the mothly wage costs for the projected team (MWC-PT) i relatio to the mothly wage costs for the curret team (MWC-CT) was calculated as follows (5) : Variace=(NPP/NCP-1) 100=% Variace=(MWC-PT/MWC-CT-1) 100=% Data aalysis The data was etered i electroic spreadsheets ad preseted i figures ad charts, usig measures of cetral tedecy. The test of sigificace betwee meas ad the Chi-square test were used, at a sigificace level of 5% to compare curret staff with projected staff. Persoel costs were aalyzed by descriptive statistics, usig the mothly wage mea by professioal category i Hospitals A, B ad C. The amouts are show i Brazilia reals. RESULTS Durig the period studied, patiets i the iteral medicie ad surgical uits of the three teachig hospitals were classified by the researchers accordig to the PCS of Fuguli, Gaidziski e Kurcgat (4). The mea daily umber of patiets was: 76 i Hospital A, 118 i B, ad 117 i Hospital C. The mea daily distributio of patiets accordig to the classificatio is show i Figure 1.

I Hospital B, the largest umber of patiets was i the miimum care category, followed by high-depedecy ad itermediate care. I Hospital C, the itermediate care category had the largest umber of patiets, followed by miimum ad high-depedecy care. Hospitals B ad C allocated, o average, oe itesive care patiet ad seve semi-itesive care patiets per day i the uits studied. Figure 2 shows mea curret daily ursig staff ad projected staff for the same uits, i accordace with Cofe Resolutio. 294/04 (3). I the two uits from Hospital A, there was o sigificat differece betwee projected teams ad curret teams, usig the Cofe method, demostratig adequate umbers for the curret ursig staff.

I all the uits from Hospital B, there was a sigificat differece betwee the umber of projected umber of urses ad the curret umber of urses, usig the Cofe method,, idicatig that the umber of urses was lower tha the proportio recommeded by Cofe. I Hospital C, there was a sigificat differece i two uits betwee the projected umber urses ad the curret umber of urses, usig the Cofe method, idicatig the umber of urses exceeded the proportio recommeded by Cofe. The other uits had a adequate umber of ursig professioals. Nursig staff costs i Hospitals A, B ad C As show i Chart 1, the mea total mothly wage costs for curret ursig staff was R$755,408 i Hospital A, R$476,506 i Hospital B ad R$ 621,791 i Hospital C. It ca be see that the mea aual hourly cost of the urse category i Hospital A was 3.24 times that of Hospital C ad 1.75 times that of Hospital B. The mea aual hourly cost of the urse category i Hospital B was 1.85 times that of Hospital C. I relatio to the ursig techicia/aide category, the mea aual hourly cost i Hospital A was 3.83 times that of Hospital C ad 1.83 times that of Hospital B. The mea aual hourly cost of this category i Hospital B was 2.09 times that of Hospital C. Mothly workig hours ( hours) were higher i Hospital C, followed by Hospitals A ad B. Mothly workig hours i Hospital C were 1.41 times that of Hospital A ad 1.7 times that of Hospital B. The workig hours of Hospital A were 1.2 times that of Hospital B. The mea hourly ad mothly cost for the miimum projected umber of ursig professioals accordig to Cofe Resolutio No. 293/04 (3) by professioal category ad daily workig hours are preseted i Chart 2, where it ca be oted that the mea mothly cost of the projected team would be R$896, i Hospital A, R$615, i Hospital B ad R$522, i Hospital C. I charts 1 ad 2, it ca be see that the qualitative ad quatitative adjustmet of ursig staff, accordig to the miimum parameters i Cofe Resolutio No. 293/04, would represet a mothly icrease of R$141, for Hospital A, by addig 13 urses ad elimiatig 5 ursig techicias/aides; a icrease of R$138, for Hospital B by addig 31 urses ad elimiatig 18 ursig techicias/aides; ad a R$99,028 reductio for Hospital C by elimiatig 8 urses ad 16 ursig techicias/aides. DISCUSSION I most of the uits studied, the ursig staff was quatitatively sufficiet, accordig to Cofe parameters.

However, with respect to the percetage distributio of ursig professioals, it was oted that, except for the uits from Hospital C, the umber of urses i the uits of Hospitals A ad B were lower tha that recommeded by Cofe. The variace i the umber of urses idicated the eed for 76.4% more urses i Hospital A ad 206.6% more i Hospital B. I Hospital C, this variace correspoded to a reductio of 15.1% i urses. This fidig corroborates the results of aother study (6) that showed that the proportio of urses i most Brazilia health istitutios was lower tha the distributio recommeded by Cofe, which represets a stadard to be achieved by hospital istitutios i Brazil. Nursig staff adjustmets, maily i terms of adjustig the proportio of urses i relatio to ursig techicias/aides, represeted a 18.7% icrease i persoel costs i Hospital A ad 29.1% i Hospital B, ad a 15.9% reductio i Hospital C. The compositio of the ursig staff, cotractual workig hours, ad wages were variables examied i order to recocile costs ad huma resources i the iteral medicie ad surgical uits of Hospitals A, B ad C. However, other variables could have a ifluece o cost estimates, such as umber of beds, care complexity ad available techological resources. Kowledge of these variables, combied with costs, could assist i the decisio-makig process regardig adjustmets i curret staff i light of care eeds ad legal requiremets. From this perspective, urses eed to determie quatitatively ad qualitatively determie the umber of professioals eeded to achieve the desired stadards of care, ad aalyze the fiacial impact of these resources o the outcome of care activities carried out by ursig teams, cosiderig that although ecoomic aspects are importat, they should ot override techical, huma, ethical ad social aspects whe makig decisios (7).

Therefore, urses also eed to seek kowledge, skills ad competecies that support egotiatios i referece to the ursig staff, demostratig that while adjustig the umber of professioals may result i higher operatig costs, it ca help reduce expeses arisig from egative care outcomes that are due to quatitative ad/or qualitative isufficiecy i professioals (7). CONCLUSION The cotributio of this study is its proposed method for qualitatively ad quatitatively evaluatig ursig staffs, as well as determiig the mea cost for staff adjustmets. The results merit careful aalysis ad iterpretatio so that decisios ca be made that will promote efficiet supply ad distributio of ursig professioals, i quatitative ad qualitative terms, to meet desired quality ad safety stadards. The use of this method i other situatios ad correlatio of the results with care ad maagemet quality idicators could help to scietifically demostrate the impact of ursig staffs o patiet outcomes ad health istitutios.
