Serial measurement of Therapeutic Intervention Scoring System-28 (TISS-28) in a surgical intensive care unit
ABSTRACT The aim of the study was to assess the use of the Therapeutic Intervention Scoring System-28 (TISS-28) in surgical intensive care unit (ICU) patients and the relationship of the score to the type of surgery, severity of illness, and outcome in these patients.
Prospectively collected data from all patients admitted to a postoperative ICU between March 1, 2004, and June 30, 2006, were analyzed retrospectively.
A total of 6903 patients were admitted during the study period (63.5% male; mean age, 62.3 years) constituting 29 140 observation days. The mean Simplified Acute Physiology Score (SAPS) II, Sequential Organ Failure Assessment (SOFA), and TISS-28 scores on the day of ICU admission were 36.9 ± 18.2, 5.8 ± 3.9, and 43.2 ± 10.8, respectively. The highest admission TISS-28 was observed in patients who underwent cardiothoracic surgery (47.7 ± 10.1), the lowest in neurosurgical patients (40 ± 9.6), and both declined during the 2 weeks after ICU admission; however, in trauma patients and those admitted after gastrointestinal surgery, TISS scores increased gradually after the first 2 to 5 days in the ICU. The TISS-28 score was moderately correlated to SAPS II (R(2) = 0.42; P < .001) and SOFA score (R(2) = 0.48; P < .001) throughout the ICU stay and was consistently higher in nonsurvivors than in survivors during the first 2 weeks in the ICU.
There are marked variations in TISS-28 scores according to the type of surgery. Therapeutic Intervention Scoring System-28 correlates with the severity of illness and outcome in these patients.

ABSTRACT: The purpose of this article was to describe an innovative quality initiative implemented by the clinical nurses specialist in medicine to facilitate the transition process between the intensive care unit and the medical wards. Safely transferring patients with complex health conditions from an area of high technology and increased monitoring, like the intensive care unit, to an area with lower nurse-to-patient ratio is an intricate process. The care of these patients, once transferred, also requires varying levels of expertise. As indicated in the nursing literature, this type of transition is often associated with high stress levels for the patient and family, as well as for the healthcare providers. To maximize patient safety and ensure optimal care for this patient population, well-defined mechanisms must be put in place. DESCRIPTION OF THE PROJECT/INNOVATION: The introduction of a formal assessment, consultation, and follow-up process conducted by a clinical nurse specialist (CNS). On average, 150 patients are assessed each year by the CNS. Among these patients, 15% are considered at high risk for complications upon transfer to the unit. INTERPRETATION/CONCLUSION/IMPLICATIONS: A systematic evaluation of patients by the CNS, before their transfer from the ICU to a medical unit, has been proven beneficial in ensuring a comprehensive patient care plan. Patients and families have verbalized that this intervention is helpful. Staff members have indicated that this safety initiative is useful in planning patient transfers. The next step would be to formally measure patient, family, and staff satisfaction with this initiative.Clinical nurse specialist CNS 11/2011; 25(6):321-6.

ABSTRACT: OBJETIVO: Examinar a validade concorrente do escore Nine Equivalents of Nursing Manpower Use Score (NEMS) em comparação ao Therapeutic Intervention Scoring System-28 (TISS-28) em uma Unidade de Terapia Intensiva Pediátrica (UTIP). MÉTODOS: Estudo de coorte prospectivo observacional, realizado na UTIP de um hospital universitário brasileiro, no período de dois anos, com uma amostra de 816 pacientes. Foram realizadas 7.702 observações de cada um dos escores. RESULTADOS: A média da pontuação máxima do NEMS foi 26,6±9,2 e do TISS-28 21,3±8,2. Em todas as médias, o TISS-28 foi inferior ao NEMS (p<0,001). Houve uma boa correlação entre eles (r2=0,704 para todas as observações). A concordância entre o TISS-28 e o NEMS foi boa, apresentando apenas 6,2% de diferença entre os escores. CONCLUSÃO: Os resultados mostraram boa correlação e concordância entre o TISS-28 e o NEMS, permitindo validar o NEMS nessa população de pacientes pediátricos.Acta Paulista de Enfermagem 12/2012; 26(2):123-129.

ABSTRACT: The physiological basis of physiotherapeutic interventions used in intensive care has been established. We must determine the optimal service approach that will result in improved patient outcome. The aim of this article is to report on the estimated effect of providing a physiotherapy service consisting of an exclusively allocated physiotherapist providing evidence-based/protocol care, compared with usual care on patient outcomes. An exploratory, controlled, pragmatic, sequential-time-block clinical trial was conducted in the surgical unit of a tertiary hospital in South Africa. Protocol care (3 weeks) and usual care (3 weeks) was provided consecutively for two 6-week intervention periods. Each intervention period was followed by a washout period. The physiotherapy care provided was based on the unit admission date. Data were analyzed with Statistica in consultation with a statistician. Where indicated, relative risks with 95% confidence intervals (CIs) are reported. Significant differences between groups or across time are reported at the alpha level of 0.05. All reported P values are two-sided. Data of 193 admissions were analyzed. No difference was noted between the two patient groups at baseline. Patients admitted to the unit during protocol care were less likely to be intubated after unit admission (RR, 0.16; 95% CI, 0.07 to 0.71; RRR, 0.84; NNT, 5.02; P = 0.005) or to fail an extubation (RR, 0.23; 95% CI, 0.05 to 0.98; RRR, 0.77; NNT, 6.95; P = 0.04). The mean difference in the cumulative daily unit TISS-28 score during the two intervention periods was 1.99 (95% CI, 0.65 to 3.35) TISS-28 units (P = 0.04). Protocol-care patients were discharged from the hospital 4 days earlier than usual-care patients (P = 0.05). A tendency noted for more patients to reach independence in the transfers (P = 0.07) and mobility (P = 0.09) categories of the Barthel Index. A physiotherapy service approach that includes an exclusively allocated physiotherapist providing evidence-based/protocol care that addresses pulmonary dysfunction and promotes early mobility improves patient outcome. This could be a more cost-effective service approach to care than is usual care. This information can now be considered by administrators in the management of scarce physiotherapy resources and by researchers in the planning of a multicenter randomized controlled trial.
