In MCZ more habitats in the form of phytomorphic heterogeneity were available to faunal species as compared to CWZ, which agreed with that of Bos et al.
Among them the wheat and brassica crop in CWZ were preferred by many species of Odonata, Hemiptera, Coleoptera, Diptera and Araneae.
Orders Orthoptera, Hemiptera, Coleoptera and Araneae were dominating in both zones with significantly greater diversity of the former three orders in MCZ and the later one in CWZ. A significantly greater diversity of Araneae could be related to relative humidity, which was lower in relatively arid climate of CWZ.
Between October 2001 and February 2002, 120 (n=94 prevention group, n=26 treatment group) patients in SAH, and between November 2003 and January 2004, 130 (n=65 prevention group, n=65 treatment group) patients in the CWZ were included.
The standard mattresses used in both hospitals were high-quality pressure-reducing foam mattresses (the Cliniplot mattress [Hill-Rom, U.S.] in the SAH and the Tempur-Pedic viscoelastic foam mattress [Tempur-Pedic, U.S.] in the CWZ).
The incidence figures did not differ significantly between the two hospitals: 5.5% in SAH and 4.9% in CWZ ([chi square]=2.10, df=l; p=0.15) (see Table 1).
The CWZ placed most emphasis on repositioning and mobilization (human approach), while the SAH most frequently used special dressings and ointments (technical approach).
Table 7 shows the estimated budget impact per pressure ulcer grade for the SAH with the predominantly technical approach and the CWZ with the predominantly human approach.
Although the length of stay in the CWZ was significantly longer than in the SAH (19.8 days vs.
